I can't imagine they would really make any difference. Only one way to find out though, cut your next bunch in a triangle and give it a go.
Yeah, I thought about that but if you'll notice they are not exactly triangles - kind of a strange star shape. That's why I was hoping to score a small package at the store to try or use as a template. All my patches are square now, but I use to get nothing but round. Can't say as I noticed any difference.
